Abstract

The invention provides an enhanced water pipe. Arc-shaped concave grooves, which sink towards the inside of the pipe, are uniformly distributed in a pipe wall of the enhanced water pipe along the axial line; the arc-shaped concave grooves extend along the whole water pipe; and connections between the arc-shaped concave grooves and the rest parts of the pipe wall are all of smooth transition. The enhanced water pipe is low in price and cost and has stronger internal compression resistance.

Description

The enhancement mode water pipe

Technical field

The present invention relates to the pipeline field, especially, is a kind of plastic water supply pipe road.

Background technique

Along with development of material technology, traditional metal water supply line is eliminated, and the substitute is various plastic water supply pipes road; Modal have PP-R pipe, PE pipe, pvc pipe, PB to manage or the like; And consider cost factor, then the relatively poor pipeline of ductility is comparatively cheap usually, manages like PP-R; And some PE pipe, pvc pipe, the relatively poor plastic pipe usage space of this kind flexibility is bigger.

But, under the severe cold situation, perhaps under the unsettled situation of hydraulic pressure, freeze in the pipeline or meet with and suppress impact in the winter time, be easy to cause the booster phenomenon, therefore, the compressive strength of this kind pipeline still awaits improving.

Summary of the invention

To the problems referred to above, the object of the present invention is to provide a kind of enhancement mode water pipe, not only Costco Wholesale is low for this enhancement mode water pipe, and has stronger inner pressure resistant performance.

The technical solution adopted for the present invention to solve the technical problems is: the tube wall of this enhancement mode water pipe is evenly equipped with the arc groove to the pipe interior depression around axis, and said arc groove extends along whole water pipe; The equal rounding off of the joining place of said arc groove and said tube wall remaining part.

Further, said arc groove has 4, so; On the cross section of this enhancement mode water pipe; The line at each said arc groove center constitutes a quadrilateral, for the change in location between each arc groove center provides the geometric condition of minimum requirements, with the restriction manufacture cost.

Further, the remaining part of said arc groove and said tube wall is extruded by plastic pipe extruder one; Said tube wall equates at the wall thickness at arc groove place and all the other places; The radius of said arc groove is 3 ~ 5 times of wall thickness.

Beneficial effect of the present invention is: this enhancement mode water pipe in use; Impact if meet with icing or strong hydraulic pressure in the water pipe, then because elastic strain will outwards take place in the existence of said arc groove; With increasing suddenly of separator tube internal pressure, strengthened the anti-pressure ability of pipeline greatly; And this enhancement mode water pipe still can be extruded by extruder continuously, only needs to change the extrusion outlet shape and gets final product, and cost is lower.

Description of drawings

Fig. 1 is an embodiment's of this enhancement mode water pipe a cross-sectional view.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

In the embodiment shown in fig. 1, the tube wall 1 of this enhancement mode water pipe is evenly equipped with four arc grooves 10 to the pipe interior depression around axis, and said arc groove 10 extends along whole water pipe; The equal rounding off of joining place of said arc groove 10 and said tube wall 1 remaining part.

It is to be noted; Said arc groove 10 can be 4 ~ 6, adopts 4 in the present embodiment, can make on the cross section of this enhancement mode water pipe; Line by each said arc groove 10 center constitutes a quadrilateral; Shown in dotted line quadrilateral among Fig. 1, according to the yielding principle of quadrilateral, just the geometric condition of minimum requirements is provided for the change in location between each arc groove 10 center; When arc groove 10 is shaped on more numbers, is easier to distortion, but, is advisable with 4 ~ 6 for restricting cost.

Said arc groove 10 is extruded by plastic pipe extruder one with the remaining part of said tube wall 1; Said tube wall 1 equates at the wall thickness at arc groove 10 places and all the other places; The radius of said arc groove 10 is 3 ~ 5 times of wall thickness.

Above-mentioned enhancement mode water pipe in use impacts if meet with icing or strong hydraulic pressure in the water pipe, then because elastic strain will outwards take place in the existence of said arc groove 10, with increasing suddenly of separator tube internal pressure, has strengthened the anti-pressure ability of pipeline greatly; And this enhancement mode water pipe still can be extruded by extruder continuously, only needs to change the extrusion outlet shape and gets final product, and cost is lower.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
